Abstract
CONTEXT: Transrectal ultrasound guidance (TUG) during prostate endoscopic surgery can optimize the procedure by reducing the risk of capsular perforation and ascertain the treatment completeness. TUG is proposed during photoselective vaporisation of prostate (PVP). OBJECTIVE: To report four cases of rectal perforations during PVP with TUG and assess their occurrence. MATERIALS AND METHODS: This is a retrospective study including prostate endoscopic surgeries with TUG, performed in two centers between November 2011 and May 2013. Rectal perforations were identified. Surgical data, treatment modalities and postoperative outcomes of rectal perforations were analysed. RESULTS: Four rectal perforations were identified among 450 surgical procedures. Median age and prostate volume were 80 years old [62-91] and 40mL [13-150], respectively. Two perforations occurred during PVP with Greenlight(®) XPS 180W. Two perforations occurred during transurethral resection of prostate or cervicoprostatic incision. Patients were treated by systematic urinary drainage associated with colostomy or direct suture. Two patients died from this complication and two patients have satisfying functional outcomes at one year. CONCLUSION: TUG during prostate endoscopic surgery could lead to rectal perforation by protusion of the prostate and therefore should be used cautiously. LEVEL OF EVIDENCE: 5.
